About our wider doorways & openings service in Surrey
Wider doorways and openings are gaps formed or enlarged in internal walls, with a lintel or steel beam carrying the masonry and loads above. They sit between a simple door change and a full wall removal: the span is shorter, but each opening still needs the right support and approval if the wall is structural.
We carry out wider doorways & openings throughout Surrey, for homeowners, landlords and builders who need the structural part done properly. That includes Banstead, Ewell and Woking, plus smaller towns and villages nearby. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
Things to plan for
- Hallway walls are often load-bearing because they line up with walls upstairs and carry the floor joists or the stairs. A wall that sounds hollow when knocked is usually a stud partition, but older homes can have timber walls that still carry loads, so the engineer checks.
- The main cost factors are whether the wall is structural, the width of the opening, what the support bears onto, how much electrical or heating work has to move, and whether you want new door linings and doors fitted as part of the job.
- In older houses, a doorway may already have a timber lintel that has rotted or a brick arch that is hard to extend. These are replaced rather than added to, and the engineer allows for soft lime mortar and any cracking found once the wall is opened.
- Older door surrounds and walls can hide asbestos in textured coatings, insulating board above doors or panelling. In buildings built before 2000 it must be identified before the wall is cut, so a refurbishment survey of the area is arranged where there is a risk.
- When an opening widens, the old threshold strip and floor finishes often stop short. Carpet, boards or tiles need joining neatly across the new width, and a change in floor height between rooms may need a threshold bar or a gentle ramp.
Four stages, one team
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Figures include our approximate regional adjustment for prices in the South East (+12%) and are rounded. How these figures are worked out.
Approvals in Surrey
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.
Local questions answered
Do I need a party wall agreement for wider doorways & openings in Surrey?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
How much do wider doorways & openings cost in Surrey?
As a guide, budget £1,100–£2,800 including VAT for widening an internal doorway in Surrey, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
How wide can I make a doorway?
That depends on the wall, what it carries and how much solid wall is left at each side for the support to bear on, and a structural engineer sets the limit. Many people go from a single door to a double-width opening, and beyond that the job starts to become a partial wall removal.
Can I move a doorway to a different position?
Usually, yes. The old doorway is blocked up and a new opening is formed with the support the engineer specifies, and both changes are dealt with together for building control if the wall is structural. Moving a door can release wall space for furniture or a better kitchen or bedroom layout.
Will widening a doorway make a mess?
There is some dust and noise, mainly on the day the opening is cut. We screen the area, protect floors along the route and use dust extraction on saws where possible. Rooms either side are affected for a day or two, while the rest of the house stays in normal use.
Can I widen a doorway in a load-bearing wall?
Yes. The extra width is spanned by a lintel or steel beam that a structural engineer specifies, sitting on solid bearings either side. Because the wall is structural, the work needs building control approval in England and Wales, a building warrant in Scotland, or a council building control application in Northern Ireland. We arrange the design and approval.
Can I stay at home while the work is done in Surrey?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
